VTHO and VET are two tokens in the VeChain Ecosystem. In the past, holding VET would result in an airdrop of VTHO.
There is no news for VET, but due to VTHO being listed on Upbit, it pumped 4x, which made many people fomo into VET, causing it to rise as well.
VET is the main token of VeChain, used for storing value and making payments within the ecosystem. VTHO is a secondary token, created from VET, used to pay transaction fees and maintain blockchain operations.
